[PATCH 1/4] engine.pl: Fix a recent breakage of the buildsystem generator

[Ramsay Jones <ramsay@ramsay1.demon.co.uk>]

Commit ade2ca0c (Do not try to remove directories when removing
old links, 27-10-2009) added an expression to a 'test' using an
'-o' or connective. This resulted in the buildsystem generator
mistaking the conditional 'rm' for a linker command. In order
to fix the breakage, we filter the out the conditional 'rm'
commands before attempting to identify other commands.
